PERFLUOROURETHANE COPOLYMER CONTAINING PERFLUOROALKYL ALCOHOL AND ISOCYANATE CO-MONOMER AND ANTI-FOULING FILM USING THE COPOLYMER

摘要

PURPOSE: A perfluorourethane copolymer and an anti-fouling film using the copolymer are provided, to enhance water repelling property, oil repelling property, anti-fouling property and non-adhesive property by improving the hydrophobicity of the surface of a film. CONSTITUTION: The perfluorourethane copolymer is obtained by copolymerizing a perfluoroalkyl alcohol represented by CF3(CF2)nCH2CH2OH and an isocyanate co-monomer, wherein n is 5, 7, 9 or 11. Preferably the isocyanate co-monomer is selected from the group consisting of toluene 2,4-diisocyanate, 4,4-methylene bis(phenyl isocyanate) and 1,6-diisocyanatohexane; and the molar ratio of the isocyanate co-monomer to 1 mole of the perfluoroalkyl alcohol is 1-2. Preferably the perfluorourethane copolymer has an average molecular weight of 1,200-1,400.
